ESPAR Antenna for Long Distance WSN Systems with Minimum Interference

다국어 초록 (Multilingual Abstract)

Recently, radio frequency identification (RFID) with ultra-high frequency (UHF) band applications became an essential part in the Internet of Things (IoT) system. Wireless sensor networks (WSNs) are an integral part of the IoT. Nowadays, it is very important to design the WSN system model in longer distance with minimum interference and optimum signal-to-noise ratio (SNR) for better communications link. In this paper, we have proposed the architecture of WSN system by designing electronically steerable parasitic array radiator (ESPAR) antenna for minimum interference. Also, the link budget (LB) for distance depending on different SNR values between the RFID tag and reader are analyzed using MATLAB simulation tools. The ESPAR antenna shows very good performance based on gain, radiation pattern, and reflection coefficient. The maximum value of gain of the proposed ESPAR antenna is obtained as 7.55 dBi which will successfully handle the interference at any directions to be communicated over long distance as compared to the previously published once papers in WSN system. The link budget analysis spectacled that the proposed article in the indoor environment could easily be applied for 20 meter.
